Description

[Detailed description of the invention] The present invention provides a cassette-type ceiling-embedded air conditioner in which an air outlet and an inlet are integrally formed in parallel on both sides of a lower panel at the bottom of the machine body. In a ceiling-mounted air conditioner, the purpose is to reliably prevent the occurrence of airflow resistance due to interference between the outlet wind force and the suction wind force, that is, the short circuit phenomenon, which inevitably occurs near the ceiling, and to ensure smooth and good air flow. Regarding short circuit prevention mechanism.

Most of the conventional ceiling-embedded air conditioners have an air outlet and an inlet formed in separate structures on the bottom of the machine, which significantly impairs the design of the ceiling and is expensive. There were certain drawbacks.

In order to solve this drawback, recently, as shown in Figure 1, a suction hole 7 inside the fuselage is provided in the center of the air ventilation passage, and a central panel 8 on the lower surface of the fuselage is opened.
A ceiling-embedded cassette type air conditioner has been developed in which an air outlet 9 and an inlet 10 are arranged in parallel on both sides of the air conditioner, but the overall structure is compact and the design is outstanding. On the other hand, since the blow-off port 9 and the suction port 10 are formed in parallel, the incoming and outgoing air mixes and rotates near the inlets of both blow-off ports, resulting in a so-called short circuit. This phenomenon occurred, and effective air conditioning could not be achieved.

The present invention focuses on the above-mentioned drawbacks, and without changing the mechanism of the air conditioner, the air outlet and the suction port are arranged in a Z-shape on each side. The present invention aims to provide a short circuit prevention mechanism in a ceiling-mounted air conditioner, which fundamentally solves the short circuit phenomenon that occurs when the air conditioner is separated from the opening, and also ensures that air is blown to the far corners of the room. It is something to do.

That is, to explain the embodiment of the present invention with reference to illustrative drawings, inside the fuselage 1 there are a blower 2, a heat exchange coil 3,
A branch duct 6 formed by separately forming a suction air ventilation passage A and an outlet ventilation passage B is arranged in the air ventilation passage 5 in which the drain pan 4 is disposed, and suction holes 7 are provided on both sides of the suction air ventilation passage A of the branch duct 6. , 7 are provided, and air outlets 9, 9 and suction port 1 are provided on both sides of the lower panel 8.
It has a configuration in which openings 0 and 10 are arranged in a Z-shape at diagonal positions.

In addition, a suction hole 7 opened in the branch duct 6,
7 is a suction air ventilation path A depending on the structure shape, dimensions, etc.
It opens at one or several places inside.

In the drawing, reference numeral 11 indicates a filter to be fitted into the suction hole 7, and reference numerals 12 and 12 indicate wind direction changing blades, respectively.

As described above, the present invention is a ceiling-embedded air conditioner formed by the body 1, the branch duct 6, and the bottom panel 8, in which the air outlets 9, 9 and the suction ports 10, 10 are arranged in tandem on both sides of the bottom panel 8, respectively. Since the air inlets 10, 10 are arranged in a Z-shape at diagonal positions on the lower panel 8, the respective air outlets 9, 9 and suction ports 10, 10 are securely connected to each other. By separating and shutting off at Since it is opened in the shape of a shape, it also has remarkable effects such as being able to supply air over the entire circumference of the room.
